The aim of this study is to investigate the impact of physical appearance attributes (in terms of color and shape) oil our affective feelings of 2D and 3D objects. Twelve colors Were studied, each consisting of 12 two-dimensional and 12 three-dimensional shapes. This resulted in 144 2D and 144 3D color-shape combinations. Each color-shape combination was assessed using 20 emotion scales in a viewing, cabinet by a Panel of observers with normal color vision. The results show that there are five factors of these 20 scales, i.e.. "activity," weight," ''heat." "softness," and "complexity". The first three factors were mainly related to color and the other two were linked with shape. (c) 2008 Wiley Periodicals. Inc.
